OSN1800V TNF5SL64D is a 2-channel STM-64 optical interface board. It is used in OptiX OSN series devices to realize the reception and transmission of 2-channel STM-64 optical signals.SL64D optical interface board belongs to TDM single board. The SL64D is a TDM board, which is used to complete the photoelectric conversion of STM-64 signals, extract and insert overhead bytes, and report alarms generated on the line.The SL64D board consists of a photoelectric conversion module, an overhead processing unit, a logic control unit, and a clock unit.The SL64D board needs to occupy one slot. Support CWDM color optical interface, CWDM optical interface supports 70km transmission distance. Supports DWDM color optical interface, DWDM optical interface supports 40km and 80km transmission distance.STM-64 optical interface supports 10km and 40km single-fiber bi-directional pluggable optical module. Supports 2-way SDH line clock. The laser safety level label indicates that the laser safety level of the optical interface is CLASS 1, which indicates that the maximum output optical power of the single-board optical interface is less than 10 dBm (10 mW).

|
Port |
- |
Displays the corresponding SDH interface. |
|
Optical Port Name |
- |
Displays or sets the optical port name. |
|
Laser Switch |
On, Off Default: on |
Displays or sets the interface laser switch status. Only the SDH optical interface board supports this parameter. Normally, the setting is "On". |
|
Optical (Electrical) Interface Loopback |
No Loopback, Inner Loopback, Outer Loopback Default: No loopback |
Displays or sets the loopback status of the SDH interface.
This function is generally used for fault localization of each SDH interface. "Optical (electrical) port loopback" is a diagnostic function, and its use will affect the service of the relevant port, so please use it with caution. In general, the setting is "No Loopback". |
|
VC4 Channel |
Example: NE(9-1001)-1-SL64D-1(SDH-1)-VC4:1 |
The corresponding VC4 channel is displayed. |
|
VC4 Loopback |
No loopback, inner loopback, outer loopback Default: no loopback |
Displays or sets the loopback status of the line unit's VC4 channel.
This function is generally used for fault localization of each VC4 channel. "VC4 loopback" is a diagnostic function, and its use will affect the service of the relevant port, so please use it with caution. Under normal circumstances, the setting is "No Loopback". |
|
VC3 Channel |
Example: NE(9-1001)-1-SL64D-1(SDH-1)-VC4:1-VC3:1 |
The corresponding VC3 channel is displayed. |
|
VC3 Loopback |
No loopback, inner loopback, outer loopback Default: No loopback |
Displays or sets the loopback status of the VC3 channel of the line unit.
This function is generally used for fault localization of each VC3 channel. "VC3 loopback" is a diagnostic function, and its use will affect the service of the relevant port, so please use it with caution. Under normal circumstances, the setting is "No Loopback". |
|
VC12 Channel |
Example: NE(9-1001)-1-SL64D-1(SDH-1)-VC4:1-VC12:1 |
Displays the corresponding VC12 channel. |
|
VC12 Loopback |
No loopback, inner loopback, outer loopback Default: No loopback |
Displays or sets the loopback status of the VC12 channels of the line unit.
This function is generally used to locate faults on each VC12 channel. "VC12 loopback" is a diagnostic function, and its use will affect the service of the relevant port, so please use it with caution. Under normal circumstances, the setting is "No Loopback". |

Optical interface |
Example: NE(9-1001)-1-SL64D-1(SDH-1) |
Displays the corresponding optical interface. |
|
Auto shutdown |
Prohibit, Allow Default: Prohibit |
Displays or sets the "Auto Off" status of the laser. Laser auto shutdown is a function to shut down the laser automatically when the optical interface does not carry service, fiber failure, or loss of received optical signal. When "Allow" is set, "On Time (ms)","Off Time (ms)" and"Long On Test Time (ms)" can be set. ". |
|
On time (ms) |
Example: 2000 |
Displays or sets the time to test whether the fiber is normal if the laser is turned on automatically after it is turned off. |
|
Off time (ms) |
Example: 60000 |
Displays or sets the time for the laser to turn off automatically (this parameter can be set only when the laser auto off function is enabled). |
|
Long open test time (ms) |
Example: 90000 |
Display or set the time to test whether the fiber is normal or not after turning off the laser, if the laser is turned on manually. |
